The first aspect of the present invention has been made in consideration of such circumstances. That is, the 1st objective of this invention is providing the duct structure, the duct apparatus, and the duct reinforcement construction method which can improve strength with a comparatively simple and lightweight structure, and the construction of a reinforcement process is comparatively simple.

Moreover, in the reinforcement technique of the conventional support, there existed the following problems.

That is, when reinforcing an existing support, it is necessary to carry reinforcement members, such as a brace and a rib, into the reinforcement construction point. In particular, when the reinforcing member is a steel material, there is also a weight, and the carry-in is troublesome and requires a lot of time.

In addition, when the reinforcement treatment is performed on the existing support by welding, it takes time for procedures related to preparation and curing. In addition, a welding machine etc. may not enter a working place by the operation | work at the narrow point in which the said long object was installed. In such a case, there existed a problem that the point which welding was difficult to generate | occur | produce etc. in support.

In addition, when the support object (long object) by a support is a duct, it is necessary to prevent the bad influence (for example, malfunction by noise) with respect to the apparatus provided in the vicinity of the duct which needs reinforcement process. Therefore, there exists a problem that the machining, welding, or melting work using electricity is limited, and there existed room for improvement in that point.

The second aspect of the present invention has been made in view of the problems described above. That is, a 2nd object of this invention is to provide the support reinforcement structure of the long object which can raise rigidity with a simple and lightweight structure, and can simplify the construction of reinforcement processing.

In addition, when the reinforcement treatment is performed on the existing fixing unit by welding, it takes time for the procedure and curing related to preparation. Moreover, as a work in the narrow point in which the long object which a support supports is extended, there existed a problem that a welding machine etc. do not enter a work place and the point which welding is difficult arises. In addition, the reinforcing member may be fixed by bolts. Also in this case, it is necessary to form a bolt hole in an adjacent structure (supported part) such as a wall using a tool such as a drill. Therefore, there is a problem that installation cannot take place at a narrow point where the installation takes time and the tool does not enter.

Moreover, when the support object (long-form object) by support is a duct, an apparatus may be installed in the vicinity of the duct which needs reinforcement process. In this case, in order to prevent the adverse influence (for example, malfunction by noise) with respect to the installed apparatus, there exists a problem that the machining, welding, or melting work using electricity is limited. In that respect, there has been room for improvement in conventional reinforcement techniques.

That is, the said fiber reinforcement member may be arrange | positioned on the surface on the opposite side to the surface which opposes the said structure of the said fixing | fixed part.

In the present invention, the fiber reinforcing member can be easily fixed to the fixing portion already fixed to the adjacent structure (supported portion) without removing the fixing portion.

In the reinforcing structure of the fixing unit, a block material for fixing to the structure (supported part) may be provided on the outer peripheral portion of the fixing unit, and a fiber reinforcing member may be formed over the block material and the fixing unit.

That is, the reinforcing structure of the fixing unit may be provided on the outer periphery of the fixing unit, and may include a block material fixed to the structure. In this case, the fiber reinforcing material may be formed over the block material and the fixing unit.

In the present invention, since the structure (supported portion) adjacent to the fixing portion and the block member is integrally formed via the fiber reinforcing member, the reinforcing portion to increase the rigidity of the fixing portion is easy.

Moreover, in the reinforcement structure of the said support fixing part, the block material may be provided with the slope which removes the step | step in the thickness direction of the fixing part formed by the structure (supported part) adjacent to the fixing part.

That is, the said block material may have the surface which opposes the said structure, and the inclined surface inclined with respect to this surface. And the said slope may be formed so that it may continue on the surface which opposes the said fixing | fixed part of the said structure, and the surface on the opposite side to the surface which opposes the said structure of the said fixing | fixed part without a step | step.

According to this configuration, when the fiber reinforcing member is formed over the fixing portion and the adjacent structure (supported portion), the step formed between the fixing portion and the structure (supported portion) is eliminated by the slope of the block material. Therefore, the fiber reinforcement member can be fixed without a gap, and more reliable reinforcement can be performed.

In the reinforcing structure of the fixing unit, the fiber reinforcing member may be sandwiched between the fixing unit and the adjacent structure (supported unit).

That is, the fiber reinforcing member may be disposed on a surface of the fixing unit that faces the structure.

According to the said structure, at the time of installation of a support, a fiber reinforcement member is formed between an adjacent structure (supported part) and a fixing part. Then, the fiber reinforcing member is in a state interposed by the structure and the fixing unit. Thereby, by this, the thickness of a fixing | fixed part can be increased and rigidity can be improved. Therefore, the reinforcing structure of the fixing unit can reinforce the bending stress generated by the support for supporting the long object.

Moreover, the reinforcing structure of the other fixing part which concerns on the 3rd aspect of this invention is the reinforcing structure of the flat plate fixing part for fixing the support for supporting a long object to the adjacent structure (supported part). In the reinforcing structure of this fixing unit, a structure (supported part) adjacent to the fixing unit is fixed by an adhesive containing a fiber reinforcing member.

That is, the reinforcing structure of the fixing unit includes an adhesive for fixing the plate-like fixing unit for fixing the support for supporting the long object to the adjacent structure. Here, the said adhesive contains a fiber reinforcement member.

According to the said structure, at the time of installation of a support, the fixing part is fixed to the adjacent structure (supported part) by the adhesive agent containing a fiber reinforcement member. As a result, the fixing portion increases in thickness by the adhesive layer formed of the adhesive. This makes it possible to increase the rigidity of the fixing unit. Therefore, the reinforcing structure of the fixing unit can reinforce the bending stress generated by the support for supporting the long object.

According to the duct structure according to the first aspect of the present invention, the strength can be improved with a relatively simple and lightweight structure, and the reinforcement treatment can be made with a relatively simple construction.

Moreover, according to the duct apparatus which concerns on the 1st aspect of this invention, strength can be improved with a comparatively simple and lightweight structure, and a reinforcement process can be made into a comparatively simple construction.

Moreover, according to the reinforcement construction method which concerns on the 1st aspect of this invention, intensity | strength can be improved with a relatively simple and lightweight structure with respect to a duct main body by comparatively simple construction.

According to the support reinforcement structure of the long object according to the second aspect of the present invention, the rigidity of the support can be improved with a simple and lightweight structure. Moreover, the construction of the reinforcement process with respect to the existing support can be simplified.

According to the reinforcing structure of the support fixing unit according to the third aspect of the present invention, the rigidity of the support fixing unit can be improved with a simple and lightweight structure. In addition, the construction of the reinforcement treatment for the fixing unit can be simplified.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to drawings.

(1st embodiment)

FIG. 1: is sectional drawing which cross | intersects the central axis P1 of the duct apparatus 1101 which concerns on 1st Embodiment of this invention, and FIG. 2 is sectional drawing along the I-I line | wire of FIG.

The duct apparatus 1101 is arrange | positioned for the purpose of evacuating the control room of a plant installation, and as shown in FIG. 2, the exhaust flow path (duct flow path) R1 is formed along the central axis P1. The duct apparatus 1101 includes a duct structure 111 in which the duct main body 11 and four fiber reinforced molded bodies 12 are joined via an adhesive layer 13, and a heat insulating material formed on the outer circumference of the duct structure 111 ( 16 and a packaging material 17 formed on the outer circumference of the heat insulating material 16.

As shown in FIG. 1, the duct main body 11 has the cross-sectional shape in which the cross-sectional shape was formed in the rectangle in the cross section which cross | intersects the direction (extension direction, center axis P1 direction) in which the exhaust flow path R1 extends. It is a duct. The duct main body 11 has a closed end surface in which a duct wall 11a made of a relatively thin steel plate is continuous via four duct edge portions 11b, and the duct wall 11a is an exhaust flow path R1. ) Is defined.

The fiber-reinforced molded body 12 is obtained by aligning carbon fibers in one direction or in multiple directions, impregnating a resin material, and molding and hardening them. Moreover, in this embodiment, an epoxy resin is used as a resin material.

As shown in FIG. 1, this fiber-reinforced molded body 12 is formed in an L shape in cross section, and is formed in each of the four duct edge portions 11b of the duct body 11. As shown in FIG. 2, the fiber-reinforced molded body 12 is formed to extend by a length substantially equal to the length in the longitudinal direction of the duct body 11 along the exhaust flow path R1.

Each fiber-reinforced molded body 12 is bonded to the duct wall 11a along the duct edge part 11b.

The adhesive layer 13 is formed between the fiber reinforced molded body 12 and the duct wall 11a, and is formed by dry-curing an epoxy adhesive.

Thus, the duct structure 111 is comprised by forming four fiber reinforced molded objects 12 in the duct main body 11 through the adhesive layer 13.

Since the fiber reinforced molded body 12 is formed in the duct edge part 11b, the duct structure 111 is a structure in which thickness increases in the range in which the fiber reinforced molded body 12 was formed. That is, the thickness of the duct structure 111 is the same as the thickness of the duct wall 11a in portions other than the duct edge portion 11b, and in the duct edge portion 11b, the thickness of the duct wall 11a and the adhesive layer ( 13) is equal to the sum of the thickness of the fiber-reinforced molded body 12.

The heat insulating material 16 is made of fiber, such as glass wool and rock wool. As shown in FIG. 1, the heat insulating material 16 is formed on the outer circumference of the duct structure 111 in a rectangle along the shape of the duct body 11. The heat insulating material 16 is based on the duct main body 11 and the fiber reinforced molded object 12.

The packaging material 17 is formed of a relatively thin steel sheet. The exterior packaging material 17 has a heat insulating material 16 in a square shape along the shape of the duct main body 11. Between this exterior packaging material 17 and the duct structure 111 is filled with the heat insulating material 16.

Such a duct apparatus 1101 may add and form the fiber reinforcement molded body 12 afterwards with respect to the duct apparatus of the structure from which the fiber reinforcement molded object 12 was removed from the said structure. That is, with respect to the structure in which the heat insulating material 16 is formed in the outer periphery of the duct main body 11, and the exterior material 17 is formed in the outer periphery of this heat insulating material 16, the fiber reinforced molded body 12 is added afterwards and the strength In some cases, the improvement may be achieved.

In this case, the construction of the duct reinforcement treatment (duct reinforcement construction method) is carried out as follows while continuing the use and exhaust of the plant control room. First, the exterior material 17 and the heat insulating material 16 are removed, and the duct edge part 11b is manually mechanically polished or chemically polished. Then, the epoxy adhesive which becomes the contact bonding layer 13 is apply | coated to this duct edge part 11b. And the fiber reinforced molded object 12 is joined to this duct edge part 11b through this adhesive agent, and the duct structure 111 is obtained. Finally, the heat insulating material 16 and the exterior material 17 are newly formed in the duct structure 111, and construction is complete | finished. In this way, the duct apparatus 1101 is obtained.

As a more specific construction method, before application | coating of the contact bonding layer 13, the primer process by an epoxy resin is performed, and the process which planarizes the unevenness of the duct surface according to the resin thickness is performed. In addition, the fiber-reinforced molded body 12 is coated with an epoxy-based impregnation adhesive resin. Moreover, surface finishing is performed with (surface finishing agent), such as an acryl urethane resin. Thereby, a non-permeable layer is formed and it becomes possible to obtain the effect as a countermeasure against salts.

As explained above, according to this embodiment, the fiber reinforced molded object 12 formed in the duct edge part 11b through the adhesive layer 13 is provided. Therefore, the thickness of the duct structure 111 of the part corresponding to the duct edge part 11b of the duct main body 11 increases. That is, in the duct edge part 11b of the duct main body 11 which is locally weak in strength, the thickness of the duct structure 111 increases. As a result, it is possible to increase the strength of bending as a whole of the duct structure 111 with a relatively simple structure.

Moreover, the strength of the whole duct structure 111 improves with the increase of the thickness of the duct structure 111 in the duct edge part 11b of the duct main body 11 can be derived from an empirical formula or a design formula.

In addition, since the fiber-reinforced molded body 12 is relatively lightweight, the weight increase of the entire duct structure 111 can be suppressed. In addition, the handling of the duct structure 111 can be made relatively easy. This can reduce the effort and time required for the construction of the reinforcement treatment.

Moreover, since the fiber reinforced molded body 12 is comparatively light weight, even if the fiber reinforced molded body 12 is bonded to the duct main body 11 using the adhesive layer 13, sufficient fixing force can be obtained. Thereby, the intensity | strength of the whole duct structure 111 can be increased with a comparatively simple structure.

In addition, since the duct structure 111 can be reinforced without any mechanical processing using electricity, it is possible to satisfy the construction conditions of prohibiting the use of electricity, welding, or melting work, and control the plant by constructing the reinforcement treatment. There is nothing to affect.

In addition, since the construction of the reinforcement treatment from the outside is structurally easy, the duct structure 111 can be easily constructed without disturbing the use of the plant control room.

Moreover, the fiber reinforced molded object 12 is formed in substantially L shape in a cross section. Therefore, the thickness of the duct structure 111 can be increased in the necessary enough range including the duct edge part 11b of the duct wall 11a.

Moreover, since handling at the time of conveyance becomes easy and workability improves, the effort and time which are required for the construction of a reinforcement process can be reduced more.

As shown in FIG. 3, the duct apparatus 1102 has a duct structure composed of a duct body 11, four fiber reinforced molded bodies 12, an adhesive layer 13, a fiber reinforced sheet 14, and an adhesive layer 15 ( 112, the heat insulating material 16 formed in the outer periphery of the duct structure 112, and the exterior material 17 formed in the outer periphery of the heat insulating material 16 are provided.

The fiber reinforcement sheet 14 is a sheet of carbon fiber, for example. The fiber reinforcement sheet 14 is in contact with the four fiber reinforcement molded bodies 12 along the duct body 11 in order in the circumferential direction in a state where tension is applied, and is wound around the duct structure 112. have. And the epoxy resin is impregnated into the fiber reinforcement sheet 14 wound by the duct structure 112. As shown in FIG. Moreover, this fiber reinforcement sheet 14 and the duct wall 11a are closely_contact | adhered so that a clearance gap may not arise between them.

The adhesive layer 15 is formed between the fiber reinforcement sheet 14 and the fiber reinforcement molded body 12 and between the duct wall 11a and the fiber reinforcement sheet 14. The adhesive layer 15 is formed by the epoxy resin impregnated in the fiber reinforcement sheet 14 penetrating the bonding surface and curing the adhesive. That is, epoxy-based impregnation adhesive resin (epoxy resin) penetrates the adhesive applied to the surface (bonding surface) facing the fiber reinforcement sheet 14 of the duct main body 11 and the fiber reinforcement molded body 12, and uses the adhesive agent. Harden.

The construction example of the reinforcement process in this embodiment is as follows. First, the primer process by an epoxy resin is given to the surface of the duct main body 11 before application | coating of the contact bonding layer 13 for fiber reinforced molded objects 12. FIG. And the unevenness | corrugation of the duct surface is planarized according to the resin thickness. Subsequently, the epoxy adhesive which becomes the adhesive layer 13 is apply | coated to the duct edge part 11b, and the fiber reinforced molded body 12 is arrange | positioned at the duct edge part 11b. Moreover, epoxy which becomes an adhesive layer 15 on the surface of the remaining part (part except the duct edge part 11b) of the duct main body 11, and the surface of the fiber reinforcement molded object 12 joined to the duct main body 11 Apply a system adhesive. And the fiber reinforcement sheet 14 is wound and arrange | positioned with respect to the duct main body 11 in the circumferential direction in the state which exerted the tension force along the duct main body 11. After the fiber reinforcement sheet 14 is formed, the duct structure 112 is coated with an epoxy-based impregnation adhesive resin. And surface finishing is further performed with acryl urethane resin etc. Finally, the heat insulating material 16 and the exterior material 17 are newly formed in the duct structure 112, and construction is complete | finished. In this way, the duct apparatus 1102 is obtained.

Moreover, although the adhesive agent apply | coated directly to the outer periphery of the duct main body 11 is apply | coated in 2 times when joining the fiber reinforced molded body 12, and when arranging the fiber reinforcement sheet 14, first, the duct main body You may apply | coat an adhesive agent over the whole peripheral surface of (11).

According to this embodiment, the effect similar to 1st Embodiment mentioned above can be acquired. Since the duct main body 11 is provided and the fiber reinforcement molded body 12 is provided with the fiber reinforcement sheet 14 formed through the adhesive layer 15, the thickness of the duct edge part 11b further increases, The strength regarding bending can be further increased.

In addition, by forming the closed end surface by the fiber reinforcement sheet 14, not only the strength regarding bending but also the strength regarding torsion and shear can be increased.

(Third embodiment)

4 is a cross-sectional view crossing the central axis P1 of the duct device 1103 according to the third embodiment of the present invention. In addition, about the component same as FIG. 1-FIG. 3, the same code | symbol is attached | subjected and description is abbreviate | omitted.

As shown in FIG. 4, the duct apparatus 1103 is equipped with the duct structure 113, the heat insulating material 16 formed in the outer periphery of the duct structure 113, and the exterior material 17 formed in the outer periphery of the heat insulating material 16. As shown in FIG. Doing. The duct structure 113 consists of the duct main body 11, four fiber reinforced molded objects 121, and the contact bonding layer 13. As shown in FIG.

Although the fiber reinforced molded object 121 is the same structure as the fiber reinforced molded object 12 mentioned above, it differs from the fiber reinforced molded object 12 by the point provided with rib part 121a, 121b.

The rib portions 121a and 121b protrude so as to extend toward the outer side of the duct body 11 (in other words, in the normal direction of the surface to which the fiber-reinforced molded body 121 is joined in the duct wall 11a), It is formed so that it may extend along the exhaust flow path R1 (refer FIG. 1). In addition, the rib parts 121a and 121b are formed in the side ends 121A and 121B of the fiber reinforced molded object 121, respectively, as shown in FIG.

In addition, since the construction of the reinforcement treatment according to the present embodiment can be carried out in the same procedure as in the first embodiment described above, detailed description thereof will be omitted here.

According to this embodiment, since the fiber reinforced molded body 121 protrudes so that it may extend toward the outer side of the duct main body 11, it is provided with the rib part 121a, 121b formed so that it may extend along the exhaust flow path R1, The intensity | strength can be made higher than 1st Embodiment mentioned above.

(Fourth Embodiment)

FIG. 5: is sectional drawing crossing with the central axis P1 of the duct apparatus 1104 which concerns on 4th Embodiment of this invention. In addition, about the component same as FIG. 1-FIG. 4, the same code | symbol is attached | subjected and description is abbreviate | omitted.

As shown in FIG. 5, the duct apparatus 1104 includes a duct structure 114, a heat insulating material 16 formed on the outer circumference of the duct structure 114, and an exterior material 17 formed on the outer circumference of the heat insulating material 16. Doing. The duct structure 114 consists of the duct main body 11, the two fiber reinforced molded objects 122, and the contact bonding layer 13. As shown in FIG.

The fiber reinforced molded body 122 has the same structure as the fiber reinforced molded body 12, but differs greatly in cross-sectional shape. As shown in FIG. 4, this fiber-reinforced molded body 122 is formed in a substantially U-shape (channel shape) as seen in cross section, and two duct edge portions adjacent to the gravity direction among the four duct edge portions 11b. It is formed over (11b). These two fiber reinforced molded bodies 122 are arrange | positioned at intervals in the width direction (horizontal direction).

Moreover, the construction of the reinforcement process by this embodiment is the same as that of 1st Embodiment mentioned above. That is, it is based on the procedure which forms the adhesive layer 13 in the substantially U-shaped part from the cross section of the duct main body 11 which carried out the primer process, and joins the fiber reinforcement molded body 122 to it. Therefore, other detailed description is omitted.

According to this embodiment, the fiber reinforcement molded body 122 is formed in substantially U shape from the cross section, and is formed over two duct edge parts 11b. Therefore, the thickness of the duct structure 114 in the part corresponding to the two duct edge parts 11b can be increased by the one fiber reinforcement molded object 122. FIG. Moreover, only by covering the fiber reinforced molded body 122 from the side surface of the duct wall 11a, the thickness of the part corresponding to the two duct edge parts 11b of the duct structure 114 can be increased. Since workability can be improved by this, the effort and time which are required for the construction of a reinforcement process can be reduced.

Moreover, the fiber reinforced molded body 122 is formed over two duct edge parts 11b adjacent to the gravity direction. Therefore, the fiber reinforced molded body 122 is not formed in the duct wall 11a formed so that it may extend in a horizontal direction. Therefore, while suppressing the increase in weight, the bending strength against the load or the own weight acting on the gravity direction can be efficiently increased.

(Fifth Embodiment)

FIG. 6: is sectional drawing crossing with the central axis P1 of the duct apparatus 1105 which concerns on 5th Embodiment of this invention. In addition, about the component same as FIG. 1-5, the same code | symbol is attached | subjected and description is abbreviate | omitted.

As shown in FIG. 6, the duct apparatus 1105 is equipped with the duct structure 115, the heat insulating material 16 formed in the outer periphery of the duct structure 115, and the exterior material 17 formed in the outer periphery of the heat insulating material 16. As shown in FIG. Doing. The duct structure 115 consists of the duct main body 11, four steel reinforcements (metal reinforcement) 18, the contact bonding layer 13, and the wire 19. As shown in FIG.

The steel reinforcement body 18 is a member which joined the side ends of two T magnetic steels in different directions, and is provided with the steel plate main body (metal plate main body) 18a, and the steel rib part (metal rib part) 18b. .

As shown in FIG. 6, the steel plate main body 18a is formed in L shape from the cross section, and is formed in the four duct edge parts 11b of the duct main body 11 through the contact bonding layer 13. As shown in FIG.

The steel rib portions 18b protrude so as to extend from the respective portions 18a1 and 18a2 formed on both sides of the duct edge portion 11b of the steel plate body 18a toward the outside of the duct body 11, respectively. have.

The wire 19 connects each of the steel ribs 18b (eight) inside the packaging material 17. In addition, the wire 19 extends over the tip of each steel rib portion 18b and is provided with a tension force. Thereby, the wire 19 presses each steel reinforcement body 18 to the duct main body 11.

In the construction of the reinforcement treatment according to the present embodiment, degreasing and filing treatment is performed on the duct edge portion 11b of the duct body 11 before the application of the adhesive layer 13 for the steel reinforcement body 18. Moreover, a file quality process is performed also about the adhesive part of the steel reinforcement body 18. FIG. Subsequently, the epoxy-based adhesive serving as the adhesive layer 13 is applied to the duct edge portion 11b, and the steel reinforcement body 18 is formed in the duct edge portion 11b. Thereafter, all of the steel ribs 8b of the steel reinforcement bodies 18 are connected by the wires 19. As a result, the reinforcement treatment is completed. Moreover, the tension force is applied to the wire 19 at this time, and each steel reinforcement body 18 is pressed against the duct main body 11. Finally, the heat insulating material 16 and the exterior material 17 are newly formed in the duct structure 112, and construction is complete | finished. In this way, the duct apparatus 1105 is obtained.

According to this embodiment, it forms in each duct edge part 11b through the contact bonding layer 13. As shown in FIG. In addition, four steel reinforcement bodies 18 having a steel plate body 18a formed in an approximately L shape and a rib portion 18b that protrudes to extend from portions 18a1 and 18a2 on both sides of the steel plate body 18a. ). Moreover, the wire 19 which connects each steel rib part 18b of the four steel reinforcement bodies 18 is provided. Therefore, compared with the case where the duct structure 115 does not have the steel reinforcement body 18, the thickness of the part of the duct main body 11 corresponding to the locally weak duct edge part 11b increases. do. That is, the thickness of the duct structure 115 becomes the sum total of the thickness of the duct wall 11a, the thickness of the contact bonding layer 13, and the thickness of the steel plate main body 18a. Thereby, the duct structure 115 is a relatively simple structure, and can increase the intensity | strength of the whole duct structure 115.

Moreover, since the steel reinforcement body 18 fixed to the duct main body 11 is equipped with the steel rib part 18b, the intensity | strength of the duct structure 115 can be increased comparatively large.

Moreover, since the duct apparatus 1105 and the duct structure 115 are equipped with the comparatively high rigidity steel reinforcement body 18, the strength can be increased significantly.

Moreover, since the duct apparatus 1105 and the duct structure 115 are provided with the contact bonding layer 13 and the wire 19, the steel reinforcement body 18 can be fixed to the duct main body 11 sufficiently.

In addition, the duct apparatus 1105 and the duct structure 115 can be reinforced by the machining without electricity.

The support reinforcement structure 21A shown in FIG. 22 forms and reinforces the fiber reinforcement plate 26 (fiber reinforcement material) with respect to the outer periphery of the support 23 which supports the duct 21 (extended object). Here, the duct 21 is provided for the purpose of evacuating the control room of a plant installation, and is provided so that it may extend along the ceiling 22 (supported part, structure) in the state supported by the support 23.

The duct 21 is a rectangular duct having a rectangular cross-sectional shape, and has a duct wall made of a thin steel plate. This duct wall forms a closed end surface which has four corners and is continuous. The space enclosed by this duct wall is the exhaust flow path R2.

As shown in FIG. 22 and FIG. 23, the support 23 is made of H-shaped steel and is fixed to the ceiling 22 via the fixing plate 25 (fixed part). Specifically, the support 23 is a pair of longitudinal members 231 and 231 disposed on the left and right sides of the duct 21 and a horizontal member 232 connecting the lower ends of the longitudinal members 231 and 231. ) In short, the duct 21 is supported from below by the cross member 232.

The fiber reinforcing plate 26 is integrally fixed to each surface of the web 23a and the flange 23b of the support 23 by an adhesive layer 27 made of epoxy-based penetration adhesive resin or the like.

Here, the fixing plate 25 to which the upper end of the vertical member 231 of the support 23 is fixed is a steel plate having a square shape in plan view, and is ceiling mounted by anchor bolts 24, 24,..., At four corner positions. It is fixed to 22.

The fiber reinforcing plates 26 (26a, 26b) are plate-shaped molded bodies formed by aligning carbon fibers in one direction or in multiple directions to impregnate the resin material. The fiber reinforcement plate 26 is relatively light weight, high strength and high rigidity. As the resin material impregnated in the carbon fiber, an epoxy resin or the like can be used, for example.

The fiber reinforcement plate 26 joined to the support 23 includes a plate-shaped fiber reinforcement plate 26a and a fiber reinforcement plate 26b. The fiber reinforcement plate 26a is formed in each of the three surfaces of the recess 23d surrounded by the web 23a and the flange 23b of the longitudinal member 231 and the cross member 232 of the support 23. .

EMBODIMENT OF THE INVENTION Hereinafter, the reinforcement structure of the support fixing part which concerns on 3rd aspect of this invention is demonstrated based on drawing.

(29th Embodiment)

The reinforcing structure (hereinafter, referred to as "reinforcement structure 31A") of the fixing unit for the support according to the present embodiment is a structure (supported portion) adjacent to the support 33 supporting the duct 31 (long-length object). It has a fixing plate 34 (fixed portion) for fixing to the ceiling 32. The reinforcing structure 31A forms the fiber reinforcing sheet 35 (fiber reinforcing member) with respect to the fixing plate 34, and reinforces the fixing plate 34. In addition, in FIG. 32, in order to make it easy to understand the structure of 31 A of reinforcement structures, among the fiber reinforcement sheets 35 formed in the pair of fixing plate 34, it is attached to the fixing plate 34 of one side (the left side of the surface). Only the formed fiber reinforcement sheet 35 is shown.

The duct 31 is provided for the purpose of evacuating the control room of the plant equipment and is formed to extend along the ceiling 32 in a state supported by the support 33.

The duct 31 is a rectangular duct whose cross-sectional shape is rectangular shape. The duct 31 is provided with four duct walls which consist of relatively thin steel plates. The duct 31 has the edge part formed by the duct wall. The cross section of the duct 31 is a closed cross section, and the space surrounded by the duct wall is the exhaust flow path R3.

32 to 34, the support 33 is made of H-shaped steel and is fixed to the ceiling 32 via the fixing plate 34 (fixed portion). Specifically, the support 33 is a pair of longitudinal members 331, 331 disposed on the left and right sides of the duct 31, and a horizontal member 332 which connects lower ends of the longitudinal members 331, 331. ) In short, the duct 31 is supported from below by the cross member 332.

31 A of reinforcement structures are provided in the outer peripheral part corresponded to each edge | side of the rectangle seen from the plane of the fixing plate 34 at the cross section and the step block 38 which is triangular shape. The reinforcing structure 31A is integrally formed by an adhesive layer (not shown) in which the sheet-like fiber reinforcing sheet 35 is formed of epoxy-based penetrating adhesive resin or the like from the surface 34a of the fixing plate 34 to the ceiling 32. It is a reinforcing structure fixed to it.

The fixing plate 34 which fixes the upper end of the vertical material 331 of the support 33 to the ceiling 32 is a steel plate of square shape (square shape) in plan view. The fixing plate 34 is fixed to the ceiling 32 by anchor bolts 37, 37,... At four corner positions. Moreover, the head part 37a of the anchor bolt 37 protrudes on the lower surface (surface 34a) on the opposite side to the surface facing the ceiling 32 of the fixing plate 34. Here, in the fixing plate 34, the surface of the ceiling 32 side which opposes the ceiling 32 is made into the back surface 34b.

The step block 38 is disposed so as to be located at the corner of the step portion of the boundary between the two sides fixing plate 34 and the ceiling 32 that are perpendicular to each other in cross section. The stepped block 38 is formed with a slope 38a for removing a step in the thickness direction of the fixing plate 34 formed by the fixing plate 34 and the ceiling 32.

That is, the step block 38 has a surface facing the ceiling 32 and a slope 38a inclined with respect to this surface. The slope 38a is formed so that it may continue on both sides of the ceiling 32 which face the fixing plate 34 and the surface 34a of the fixing plate 34 without a step.

The fiber reinforcement sheet 35 includes a pair of first fiber reinforcement sheets 35A and 35A and a pair of second fiber reinforcement sheets 35B and 35B. The first fiber reinforcement sheets 35A and 35A have substantially the same dimensions as the width dimensions of the fixing plate 34. The 2nd fiber reinforcement sheets 35B and 35B have the dimension substantially the same as the width dimension of the flange 3b. The first fiber reinforcement sheets 35A and 35A are disposed on a pair of sides facing each other in the width direction of the flange of the support 33 among the four sides of the rectangular fixing plate 34 in plan view. Similarly, the 2nd fiber reinforcement sheet 35B, 35B is arrange | positioned on the pair of sides which mutually oppose each other in the width direction of the web of the support 33 among 4 sides of the rectangular fixing plate 34 by planar view, respectively. It is.

The fiber reinforcement sheet 35 (35A, 35B) is a sheet-like member in which carbon fibers are aligned in one direction or in multiple directions and impregnated with a resin material, which is relatively light in weight and has high strength and high rigidity. An epoxy resin etc. can be used as a resin material impregnated to carbon fiber, for example.

Moreover, the length dimension (length dimension of the direction orthogonal to the direction of the side of the fixing plate 34 in which the fiber reinforcement sheet 35 is arrange | positioned) of the fiber reinforcement sheet 35 is determined as follows, for example. When one end portion in the longitudinal direction of the fiber reinforcement sheet 35 is disposed at a position in contact with the support 33 (the vertical member 331) on the fixing plate 34, the other end portion is positioned on the ceiling 32. do. In addition, the position of the edge part of the fiber reinforcement sheet 35 on the ceiling 32 can be set arbitrarily.

The adhesive layer is formed between the fixing plate 34 and the fiber reinforcing sheet 35, between the step block 38 and the fiber reinforcing sheet 35, and between the ceiling 32 and the fiber reinforcing sheet 35, respectively. . The adhesive layer is formed by drying and curing the epoxy adhesive.

The reinforcing structure 31A can improve the strength by adding the fiber reinforcing sheet 35 to the fixing plate 34 of the support 33 afterwards.

Construction of this reinforcement structure 31A is the following procedure with respect to the fixing plate 34 of the support 33 in the state which supported this duct 31, continuing the exhaust in the duct 31 shown in FIG. Is carried out.

First, the fixing plate 34 is subjected to the undertreatment. That is, on the surface 34a of the fixing plate 34, a base material is given to the sticking part for sticking the fiber reinforcement sheet 35. FIG. This base treatment is mechanical polishing or chemical polishing by hand, for example. After this base treatment, an epoxy adhesive serving as an adhesive layer is applied to the surface on which the base treatment is performed. And the fiber reinforcement sheet | seat 35A, 35B previously formed in the magnitude | size of the sticking part of the fixing plate 34 is affixed on the predetermined sticking part of the fixing plate 34 with an adhesive agent. By the above, construction is complete and reinforcement structure 31A is obtained.

As a more specific construction method, before the application of the adhesive layer to the fixing plate 34, the fixing plate 34 is subjected to a primer treatment with an epoxy resin. And the unevenness | corrugation of the surface 34a of the fixing plate 34 is processed according to the resin thickness of an epoxy resin.

Thus, in this reinforcement structure 31A, the fiber reinforcement sheet 35 is affixed on the surface 34a and ceiling 32 of the fixing plate 34 with an adhesive agent, and is bonded. By the reinforcing structure which does not require such welding, the thickness of the fixing plate 34 can be increased to increase rigidity. Thereby, reinforcement with respect to the bending stress generated by the support 33 supporting the duct 31 can be performed.

In addition, the reinforcing structure 31A does not require welding, even when construction is performed at a point where welding is difficult, for example, in a narrow point where welding equipment or the like does not enter. Therefore, the reinforcing structure 31A can reinforce the fixing plate 34 easily and reliably, and can reduce the effort and time required for the construction of the reinforcing treatment.

Moreover, since the relatively lightweight sheet member like this embodiment can be employ | adopted as the fiber reinforcement sheet 35, handling of the reinforcement structure 31A at the time of construction of a reinforcement process can be made easy.

In addition, since the fiber reinforcing sheet 35 is formed over the fixing plate 34 and the ceiling 32, not only the thickness of the fixing plate 34 is increased but also the fiber reinforcing sheet fixed to the fixing plate 34 ( 35 is fixed to the ceiling 32. As a result, the fixing plate 34 and the ceiling 32 are formed more integrally. Therefore, the reinforcing structure 31A can easily perform reinforcement which raises the rigidity of the fixing plate 34.

Moreover, the fiber reinforcement sheet 35 is arrange | positioned on the surface 34a on the opposite side to the surface which opposes the ceiling 32 of the fixing plate 34. As shown in FIG. Therefore, the reinforcing structure 31A can easily fix the fiber reinforcing sheet 35 to the fixing plate 34 already fixed to the ceiling 32 without removing the fixing plate 34. .

Moreover, the step block 38 fixed to the ceiling 32 is arrange | positioned at the outer peripheral part of the fixing plate 34. As shown in FIG. The reinforcing structure 31A is a reinforcing structure in which the fiber reinforcing sheet 35 is formed over the fixing plate 34 and the ceiling 32 via the step block 38 between the ceiling 32. That is, the fixing plate 34, the step block 38, and the ceiling 32 are integrally formed by the fiber reinforcing sheet 35.

In addition, the step formed between the fixing plate 34 and the ceiling 32 is eliminated by the slope 38a of the step block 38. That is, a step is formed between the surface opposing the fixing plate 34 of the ceiling 32 and the surface 34a of the fixing plate 34. However, the slope 38a is formed on both surfaces of the ceiling 32 and the fixing plate 34 so as to be continuous without a step. Therefore, the fiber reinforcing sheet 35 can be fixed to the fixing plate 34, the step block 38, and the ceiling 32 without a gap.

By the above structure, 31 A of reinforcement structures can implement more reliable reinforcement.

As described above, according to the reinforcing structure 31A of the present embodiment, the rigidity of the fixing plate 34 is increased in a simple and lightweight structure. Moreover, the construction of the reinforcement process with respect to the existing fixing plate 34 can be simplified.

Next, another embodiment of the reinforcing structure of the fixing unit for a support according to the third aspect of the present invention will be described based on the accompanying drawings.

It is. The fiber reinforcement sheet 35C and the fourth fiber reinforcement sheet 35D are joined to the fixing plate 34 and the ceiling 32 by an adhesive layer. As a result, the fiber reinforcement sheet 35C and the fourth fiber reinforcement sheet 35D are fixed from the fixing plate 34 over the ceiling 32. That is, a pair of 3rd fiber reinforcement sheet 35C and a pair of 4th fiber reinforcement sheet 35D fixed to the fixing plate 34 are respectively located in the both sides of the support 33, and the both ends of each sheet are It is fixed to the ceiling 32.

Moreover, the bolt hole 5a is formed in each fiber reinforcement sheet 35C, 35D. The bolt hole 5a is formed so that the head 37a of the anchor bolt 37 can be accommodated in the position corresponding to the anchor bolt 37 which fixes the fixing plate 34 to the ceiling 32. Thereby, the fiber reinforcement sheets 35C and 35D can be fixed to the fixing plate 34 without a gap even around the head 37a of the anchor bolt 37.

(35th Embodiment)

As shown in FIG. 43, the reinforcement structure (reinforcement structure 31F) of the support fixing part by 35th Embodiment is a fiber in the back surface 34b (surface opposing the ceiling 32) of the fixing plate 34. As shown in FIG. It has the structure which the reinforcement sheet 35 (35I) joined. At this time, both surfaces of the ninth fiber reinforcing sheet 35I facing the ceiling 32 and the surface on the opposite side thereof are bonded to the ceiling 32 and the fixing plate 34 via the adhesive layer.

Here, an example of the construction method of the reinforcement structure 31F is demonstrated. First, the ninth fiber reinforcement sheet 35I is fixed to a predetermined position of the ceiling 32 via an adhesive layer. Next, an adhesive layer is formed on the surface 5d (lower surface) of the ninth fiber reinforcing sheet 35I bonded to the ceiling 32. The adhesive layer is formed by applying an adhesive. Next, it adhere | attaches on the ceiling 32 with the contact bonding layer in which the fixing plate 34 was formed. Thereafter, the four corners of the fixing plate 34 are fastened to the ceiling 32 by the anchor bolts 37. The reinforcement structure 31F is obtained by the above.

The reinforcing structure 31F of the present embodiment is formed by sandwiching the ninth fiber reinforcing sheet 35I between the ceiling 32 and the fixing plate 4 at the time of installation of the support 33. Thereby, the rigidity can be increased by increasing the thickness of the fixing plate 34, and reinforcement can be performed to the bending stress generated by the support 33 supporting the duct 31.

In addition, in the reinforcing structure 31F according to the thirty-fifth embodiment shown in FIG. 44, instead of the ninth fiber reinforcing sheet 35I, an epoxy adhesive containing fiber reinforcing members such as carbon fibers may be employed. That is, the structure which the adhesive layer of embodiment mentioned above doubles as a fiber reinforcement member may be sufficient.

In this case, when the support 33 is installed, the fixing plate 34 is fixed to the ceiling 32 by an adhesive containing a fiber reinforcing member, so that the fixing plate 34 is increased in thickness by an adhesive layer by an adhesive. It becomes a structure made. Since it becomes possible to improve rigidity by this, reinforcement with respect to the bending stress produced by the support 33 which supports the duct 31 can be implemented.

As mentioned above, although embodiment of the reinforcing structure of the support fixing part which concerns on 3rd aspect of this invention was described, this invention is not limited to the said embodiment, It can change suitably in the range which does not deviate from the meaning.

Moreover, in the said embodiment, as a shape of a support, it is set as the structure which consists of a pair of longitudinal material 331,331 and the horizontal material 332 which connects the lower ends, and the duct 31 is made of the horizontal material. Although supported from below, it is not limited to being support of such a shape. In addition, you may use not only H-shaped steel but L-shaped steel, spherical steel, steel pipe, etc. as a support material.

In the said embodiment, although the external shape of the fixing plate 34 is substantially square in plan view, an external shape is not restrict | limited in particular.

In addition, in the said embodiment, although the fixing plate 34 is fixed by the several anchor bolt 37, it is not restrict | limited to the structure by such a fixing form. For example, the studs formed on the rear surface 34b of the fixing plate 34 can fix the fixing plate 34 to the ceiling 32 (supported portion, structure). In the case of such a stud, the bolt head 37a like this embodiment does not protrude on the surface 34a of the fixing plate 34. Therefore, it is possible to omit the bolt hole 5a of the fiber reinforcement sheet 35 corresponding to the position of this head part 37a.

The reinforcing structures 31A to 31E of the twenty-ninth to thirty-fourth embodiments are configured to form the fiber reinforcing sheet 35 on the surface 34a side of the fixing plate 34. The reinforcing structure 31F of the 35th embodiment has a structure in which the fiber reinforcing sheet 35 is formed on the back surface 34b side (ceiling 32 side) of the fixing plate 34. However, the reinforcing structure 31F may be configured to form a fiber reinforcing member on both surfaces (surface 34a, back surface 34b) of the fixing plate 34.

In addition, in the said embodiment, although the sheet-like fiber reinforcement sheet 35 is employ | adopted as a fiber reinforcement member, it is not limited to this. The fiber reinforcing member may be joined to the fixing unit via an adhesive using a fiber reinforcement molded body molded into a predetermined shape and thickness dimension.

Moreover, the structure, such as a member, the length dimension, the thickness dimension, the number of sheet layers, a shape, the installation range with respect to a fixing | fixed part, etc. of the fiber reinforcement sheet 35 can be changed suitably according to the shape, the dimension, etc. of a fixing | fixed part.

In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace the component in said embodiment with well-known component suitably, and you may combine said embodiment suitably.
